PIC16F690-I/ML - 20MHz 8-Bit Flash MCU | Microchip
MPN: PIC16F690-I/ML ✓ Hoạt độngPIC16F690-I/ML Tóm tắt
A PIC16-family microcontroller is an 8-bit RISC controller designed for compact embedded systems, industrial equipment, consumer products, and low-power sensing nodes. The PIC16F690 belongs to the mid-range x14 PIC architecture and integrates flash program memory, data EEPROM, GPIO, timing, and communication resources into one device. Its 20 MHz maximum clock speed supports deterministic control tasks while the nanoWatt feature supports low-power operation when the application does not require continuous processing.
Key verified features include a 20 MHz clock speed, 7 KB of flash program memory, 256 bytes of RAM, 12 I/O ports according to the distributor listing, and a wide 2.0 V to 5.5 V operating-voltage range identified on Microchip's product page. The device is supplied in a 20-QFN 4 x 4 mm package, making it suitable for compact PCB layouts where a small surface-mount footprint is more important than a larger leaded package.
The PIC16F690-I/ML is suitable for compact control systems, sensor interfaces, actuator controllers, low-power monitoring nodes, and small industrial products. Its integrated EEPROM supports nonvolatile parameter storage, while the 8-bit CPU architecture is appropriate for supervisory logic, state machines, key scanning, LED control, and communication-interface coordination. Designers should confirm peripheral availability, pin multiplexing, clock configuration, and programming compatibility against the manufacturer datasheet before finalizing a new design.
Because the verified distributor snippets conflict on the package description and one result incorrectly associates SO-14 packaging with this MPN, the 20-QFN package shown by DigiKey is used here as the authoritative ordering interpretation. Verify the package drawing, exposed-pad requirements, pin assignments, and programming configuration on Microchip documentation before PCB release.
This product record combines the verified manufacturer and distributor information, clearly identifies uncertain package details, and provides selection guidance for engineers comparing PIC16F690 package variants and compatible replacements. Confirm current stock and lead time with authorized distributors because the verified LCSC result indicates availability but does not provide a complete quantity schedule.

Ứng dụng tiêu biểu
PIC16F690-I/ML phù hợp cho 6 Áp dụngs: Compact Industrial Sensor Controller, Low-Power Environmental Monitoring, LED Lighting Control, Battery Management Front Panel, Communication Interface Gateway, Consumer Appliance Control.
Compact Industrial Sensor Controller
PIC16F690-I/ML fits a compact sensor-node controller where a 20 MHz 8-bit CPU, 256 bytes of RAM, and flash program memory are sufficient for state-machine logic. The device can coordinate sensor sampling, digital filtering, threshold decisions, status LEDs, and local actuator commands while its 2.0 V to 5.5 V family range supports common embedded rails. The 20-QFN 4 x 4 mm package helps reduce board area, but the exposed-pad and land-pattern requirements must be confirmed from Microchip package documentation. Use the EEPROM for calibration constants and serial numbers, subject to the manufacturer's endurance and write-time limits. Validate peripheral multiplexing and pin assignments in the final firmware because the verified snippets do not enumerate every peripheral function.
Được đề xuất
Low-Power Environmental Monitoring
PIC16F690-I/ML is appropriate for a battery- or line-powered environmental monitor because the manufacturer identifies nanoWatt technology and the device combines flash, EEPROM, and RAM in one 20-QFN package. A firmware design can wake periodically, sample an external sensor, compare readings against stored thresholds, and return to a low-power state. The 256 bytes of RAM supports small working buffers, while EEPROM can retain calibration or logging parameters, although frequent writes require careful budgeting for endurance. The 2.0 V to 5.5 V family range helps align with low-voltage sensors and regulated rails. Confirm sleep-current values, wake-up timing, ADC behavior, and oscillator start-up requirements in the Microchip datasheet.

LED Lighting Control
PIC16F690-I/ML can be used in a compact LED-lighting controller for status indicators, small architectural fixtures, or multi-channel LED systems driven by external transistor stages. Its 20 MHz clock provides enough timing resolution for PWM-style update logic, while 256 bytes of RAM can hold counters and control variables. The 20-QFN package reduces board footprint in space-constrained assemblies, and the 2.0 V to 5.5 V operating range supports common low-voltage rails. External MOSFETs, gate drivers, current-sense resistors, and protection components will determine the achievable LED current. Confirm timer, PWM, and comparator resources on the exact device revision and verify that the selected package exposes every required output pin.

Battery Management Front Panel
PIC16F690-I/ML is suitable for a small battery-management front panel that must coordinate current measurement, button input, relay control, status indication, and fault reporting. The MCU's flash memory supports updateable control logic, while EEPROM can preserve configuration values and event counters. Its small 20-QFN 4 x 4 mm package is useful where the board must fit behind a display or enclosure. The design should use external current-sense, protection, and switching components because the supplied sources do not specify the MCU's integrated analog converter channel count or absolute electrical limits. Choose external power components for the actual battery voltage and current, and validate protection behavior across charging, standby, load, and transient conditions.

Communication Interface Gateway
PIC16F690-I/ML can serve as a small protocol-conversion or gateway controller in equipment that requires a modest serial and logic interface. A 20 MHz 8-bit MCU can parse incoming frames, maintain a compact state table, update indicators, and forward control messages through UART, SPI, or other available resources after exact pin multiplexing is confirmed. The 256-byte RAM is sufficient for lightweight buffering but not high-throughput streaming, so protocol designs should use DMA-like external buffering or a higher-performance MCU when required. The 2.0 V to 5.5 V range can simplify interface-level planning, while level shifters or dedicated transceivers may still be required. Verify the actual serial peripherals, direction pins, and electrical timing on the manufacturer datasheet.

Consumer Appliance Control
PIC16F690-I/ML is applicable to compact consumer appliances and embedded control products where a deterministic 8-bit controller manages buttons, display segments, relays, and safety-related state. The 20 MHz clock supports fast control-loop execution, and the flash architecture simplifies production programming and field updates when the board supports the appropriate programming workflow. The 20-QFN footprint helps fit dense appliance electronics, although its small size increases sensitivity to assembly capability and thermal-pad handling. Use nonvolatile EEPROM for user settings and counters, and keep high-current loads on external switching stages. The verified operating range of 2.0 V to 5.5 V supports common low-voltage control rails, but the final design must verify absolute maximum ratings and peripheral limits.

Ghi chú thiết kế
Treat the PIC16F690-I/ML as a compact 20-QFN 4 x 4 mm surface-mount part and follow the official Microchip package drawing for pad geometry, pin-1 orientation, solder mask, and land pattern. Confirm whether the selected package requires an exposed thermal pad and connect it to the recommended ground plane. Do not derive the footprint from the conflicting SO-14 wording in one search result; use the package associated with the full ordering code.
Design the supply rails and decoupling around the verified 2.0 V to 5.5 V family operating range, while checking the individual pin and peripheral limits in the manufacturer datasheet. Place required bypass capacitors close to the supply and ground pins, provide adequate return-current paths, and verify brownout, reset, and power-up behavior with the actual clock and load. The supplied sources do not provide a complete capacitor or absolute-maximum table, so those values must not be guessed.
Keep sensitive sensor inputs, programming signals, and communication lines away from fast switching nodes and noisy return paths. Because this is a mixed embedded-control device, validate input thresholds, timing margins, pin multiplexing, and peripheral configuration in the final schematic. If the MCU drives relays, LEDs, or external converters, isolate high-current switching paths from analog and reference returns and test the assembled board for startup and switching transients.
The most significant procurement and design risk in the supplied data is package and ordering-code ambiguity. One snippet lists an SO-14 package even though the target DigiKey result identifies a 20-QFN 4 x 4 mm part. Verify the full MPN, package drawing, pin table, temperature grade, programming configuration, and lifecycle status before substitution. Do not assume that a related suffix such as /SO, /SS, /P, or VAO is interchangeable without checking the physical footprint and firmware compatibility.
The supplied data confirms a compact QFN package but does not provide verified thermal resistance, maximum power dissipation, or exposed-pad requirements. Use the manufacturer's package and absolute-maximum data for the selected orderable part, then estimate dissipation from the actual supply voltage, I/O loading, and clocking mode. Keep copper available for thermal spreading where the package drawing requires it, and validate junction temperature across ambient temperature and worst-case I/O activity before production release.
Thông tin tuân thủ
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than inferred from the package or manufacturer name.
